Lindalou, there is some good info on this in the book, "Adrenal Fatigue, the 21st Century". But I really suggest you find someone to help you with these things instead of purchasing and trying them out on your self. The saliva test includes measuring your cortisol, DHEA, thyroid, testosterone and others and will help the ND or MD that you have determine if and what you need. If you "Google" DHEA, Pregnenolone and Progesterone, you will see that there are side effects and one must be careful when taking them, sometimes only for a short amount and that they work in tandem with thyroid. I would be asking Dr. Peatfield his thoughts when you see him and if he can't help you, ask him who can.

Right now I am in the process of doing what you are talking about and mercury has a role to play in it and its not as easy as people want you to think when we've got other things going on.

Here's the link to the center I'm going to and they have lots of good info on there about hormones, thyroid, adrenal etc.
